If you thought there was no room in the app marketplace for any more photo apps, Vapp, an app for taking jitter free photos, might make you think twice.

Have you ever fumbled your iPhone when trying to take a photo and ended up with a blurred image. Vapp is a solution to that eliminates your finder from the process of snapping the shot you want - simply make a sound to trigger it. 

It also solves the problem of wanting to be in the shot  without having to hold th camera above your head at arms length. While other self-timer solutions require you to set up the phone, hit a button and wait - often leading to awkward situations where people walk in format of you or you lose patience and grimace at the wrong moment - with Vapp you can pose and shout or click your fingers. You can adjust the sensitivity to take account of the level of ambient noise simply by sliding the bar on the right side of the screen up and down.

Great idea - why didn't I think of it first?
